Application filed May 23, 1914. Serial No. 840,510.

To all whom it may concern:

Be it known that l, 1WILLIAM H. NELSON, a citizenof the United States of'America, and a resident of Hazleton, Iowa., have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to improvements in sash-fasteners, and the object of my invention is, rst, to furnish fastening 'means for upper and lower sashes of a window-frame, adapted to permit of the adjustment and holding in a desired position of either sash relative to said window-frame; second, to

arrange the parts of said fastening-means so that they will be inaccessible to any one operating from the outside of the window, thus making it virtually a burglar-proof j fastening. f

Thesebbjects I have accomplished by the lmeans which are hereinafter fully described and claimed, and which are illustrated in the accompanying drawings, in which:

F igure/ 1 .is a horizontal section through adjacent parts of two window-sashes, with the abutting jamb or the window casing showing my improved fastening-means seat ed in said casing in a position tol lock the said sash in certain positions, parts of .said structures being brokenaway.` Fig.v 2 is an elevation of said Y"window-jamie, said sashes and my improved sash-fastener, vwith the y cover removed from the casing of the latter.

Fig. 3'is an upper plan view off-the sashfa'stener easing alone, with the contents removed. Fig. e is an upperplan view ofsaid casing, showing the 'movable spring-controlled bolts seated` therein, with the parts which ordinarilyare superposed thereon removed. Fig. 5 is a perspective view of the said sash-fastener casing, with the sliding closure in place. Fig.k 6 is .a perspective view of one of the sliding bolts of said device. Fig. 7 is a perspective view of the slidable keeper for the two sliding '-bolts. Fig. 8 is a perspective view of one of the flat springs. Fig( 9 is a perspective view of the detachable securing means for the shifting- Similar numerals of reference denote correspondingl parts throughout 'the 'several views. f

My said invention is an improvement upon my sash-fastener, which was patented tome bylv the United States, Julyv 22, 1902, under My improved sash-fastener comprises an oblong casing 1, open at the top, a. slide cover 2 to close said casing. Thebottom of said casing is divided by a relatively low medial longitudinal partition Vor ridge 6, end to end, integrally, and on opposite sides of said ridge and somewhat staggered with relation to each otherare the rectangular openings 3 and i in the bottom of the casingof suicient length to permit the bolts 8 and 27 of the slides 7 to project therethrough, and permit the free movement therealong.

The slides y7 and 15 are seated in oblong parallel seats on opposite sides of said ridge 6, and said slides have on their diminished ends 10 and 16, respectively, parallel springs 12 and 17 mounted thereon, with the other ends of said springs bearing against the adjacent end walls of said casing. Said slides have projections 9 and 14C, respectively, proj ecting oppositely from the bolts 8 and 27.

The numeral 16a represents aVslide-body which is of an oblong shape, with staggered recesses 17a and 21 on its opposite longitudinal sides, and having at its ends the parts 18 and 22 bent over at right angles upwardly, and provided with notches 20 and 23, respectively, near one side of each, but located oppositely'relative to each other and to the body part 16. The end projection 18 has a threaded aperture 19 adapted to receive the threadedend of 'a screw 30, the latter having an enlarged portion beginning at the shoulder 29 and terminatingwith a finger-piece or head 28. Y v

The slide-body 16L is placed within'v the casing 1 4so that its opposite recesses 21 are located to receive the projections 9 andrlli, respectively, on the slides 7 and 15. The numerals 24: and 39 denote similar flat end, and each being provided'with a projecting part 25 or 40, extending to one side thereof. These springs are seated within the casing, as indicated, in Fig. 2, where the springs, eachhaving an aperture 26 near one spring 24 is secured by a rivet passed tions 9 and 14 of the slides 7 and 15,4 and prevent said projections ordinarily passing them when being moved toward them.

Referring now to Figs. l and 2, the numeral 34 denotes one of the jambl or `side parts of a window-casing, having the upper and lower window-sash 35 and 36 seated in proper movable relation thereto, said sashes having on their inner vertical angles of the side stiles the squared sockets 37 and 38, respectively, which are ordinarily vertically staggered with relation to each other. These sockets are in line with the bolts 8 and 27, respectively, when said bolts are, as shown in Fig. 1, seated in said sockets and held there by the yielda-ble resilient pressure of the springs 12 and 17 The jamb 34 has a cavity 41 in its part, which projects into a room, and said jamb is also recessed to permit the passage of the screw 30 through said jamb and chamber 41, as shown. The shoulder 29 of said screw is adapted to engage the inner wall of the cavity 41 to form a stop for the screw.

Referring now to Fig. 9, the numeral 31 denotes an escutcheon centrally orificed to receive said screw 30 slidably. The escutcheon has, in its upper part, a channel part 32, open at the top and bottom, and whose channel is adapted to receive a slide bolt 33 having its upper end bent over to form the finger-piece. The lower end of said bolt, when in its lowered position, is adapted to be received below said raised part 32 into a transverse groove or notch 34 on the screw 30.l By the use of this bolt 33, the screw 30 may be prevented from turning and prevented from being pulled in or out. Since the screw 30 is detachably secured to the bent-over end of the slide-body 16, it is evident that when the screw is pushed in, the bolt 27 is pushed out from the sash 36 to` clear and permit the raising or lowering of said sash to a desired distance, the bolts being housed in the notch in the guide strip. When the screw 30, by means of its fingerpiece 28, is pulled out, the opposite bolt 8 is released from the sash 35, and the other sash becomes locked by the releasing of the bolt 27 and its being moved back into its socket 38 by means of the spring 17.

When the screw 30 is detached from the slide-body 16, the fastener has both its bolts 8 and 27 retracted into the sockets 37 and 38, respectively, by the action thereon of the springs 12 and 17. The bolts cannot be displaced from these locked positions with the sashes except by the use of some means from the inside of the room for shifting the slidebody 16 to and fro, which would not be practical without the use of a similar screw 30. The fastener, therefore, is practically a burglar-proof one, and cannot be released from the sashes by the use of any ordinary 'means It will be noticed that the bolts 8 and 27 cannot be displaced from the recesses 37 and 38, respectively, by slipping a thin piece of steel, such as a knife blade, between the sash and the jamb and against either. This is due to the fact that the projections 9 and 14, respectively, are stopped by the projecting parts 25 and 40 on the flat springs 24 and 29, respectively, which prevents the withdrawal of the bolts. However, when the slide-body 16 is moved in either directionby the use of the finger-pieceI 28 connected thereto, one or the other spring is acted upon by the means of the projection 18 or 22 in sliding thereover to push said spring inwardly, thereby withdrawing inwardly the projections 25 or 40, respectively, and out of the path of movement of the projections 9 or 14 ordinarily stopped thereby. The continued movement of the slide-body in the same direction will then push over the projection 9 or 40 enough to release the bolt which is integral therewith rfrom the desired sash to be unfastened. It is obvious that a different form of stop from those easily manipulated by anyone .without the window.

Havingk described my invention, what I claim as new, and desire to secure by Letters Patent, is:
